TOY AEROPLANE.

Application filed June 20, 1925;

This invention relates to toys in the form of a foot propelled aeroplaneand among the objects of the invention are the provision of an articleof the character set forth which is simple in construction, effective inaction, and which can be made to simulate an aero plane. The devicepossesses other features of novelty and advantage which with theforegoing will be set forth at length in the following description,wherein I will set forth in detail that form of embodiment of theinvention, which I have selected for illustration, in the drawingaccompanying and forming part of the present specifica tion. I am notrestricted to this exact disclosure. 1 may depart therefrom in a numberof respects within the scope of the invention defined by the claimfollowing such description.

Referring to the drawing:

Fig. 1 is a perspective view of a toy aeroplane involving the invention.i

Fig. 2 is a top plan view of the rear part of the structure showing thebody broken away.

F 8 is a side elevation of the rear part of the structure.

Fig. i is a section on the line 4 1 of Fig. 3.

Like characters refer to like parts throughout the several views.

The'body 2 is made of suitable material such as sheet metal. the body isan aileron as 3. The body on the upper side thereof, near the center,has a depression, as which is adaptable to be occupied by a youngstercontrolling the ap pliance, whose feet are on the treadles, as 5,attached to the cranks 6, to which are connected rods 7 extendingrearwardly and connecting at their ends to crank arms 8, associated withthe rear wheel 9.

The crank arms 8, are, as stated, connected with the shaft 10 of therear ground wheel 9. The tire of said wheel 9 engages at its upper endthe shaft 11., which carries rigidly a bevel gear 11, which meshes withthe pinion 12 rigid with the rear end of the shaft 13, the forward endof which is rigidly connected with the fan 14 on the front of thestructure, as shown in Fig. 1. It will be clear that an occupant of thedepression 4, having his feet on. the treadles 5, turns the treadles andthus reciprocates the rods 7 causing revolutions of the cranks 8 and Onthe upper side of- Serial N 0. 38,434.

the consequent rotation of the ground wheel 9 to turn through thedescribed connections the fan 14. The shaft 11 is furnished withdepending studs 15 extending through perforations at the upper sides ofthe arms 16 which are connected at their lower ends with the shaft 10,the studs 15 being encircled by the coiled push springs 18, which act attheir lower ends against nuts 19, threaded on the studs 15, and at theirupper ends bear against the lateral extensions of the arms 16, asillustrated clearly in Fig. 4.

Extended through the upper portion of the body 2 is a spindle, as 20,stepped at its lower end with bearing 21, rigid with the frame 22 andhaving associated mechanism for turning the vehicle and operativelyconnected with the strut 23, which is jointed to arms 2% extendingrearwardly from the front axle 25, which is equipped with ground wheels26, as shown in Fig. 1. It should be noted that the stub axles 25 arepivoted at their ends to the frame 22.

The body 2 is furnished with suitable aeroplanes as 27.

The action of the appliance is as follows: The occupant of thedepression or seat f having his feet upon the treadles 5 will revolvethe treadles and reciprocate thus the links 7 to revolve the cranks 8,and thus through the described connections rotate the wheel 9 causingthe vehicle to travel along the ground. Owing to the rotation of wheel 9the connections with the propeller 14 will rotate the propeller givingthe vehicle a rapid motion on the ground and apparently sailing.

What I claim is:

In a wheeled toy, the combination of a body provided with wheels on theunder side, planes on the forward end of the body, a shaft mountedlongitudinally on the body, a propeller on the forward end of the shaftand situated between the planes, a shaft mounted transversely on thebody at the rear end thereof and operatively connected to the firstnamed shaft and having driving engagement with one of the wheels underthe body, bearings supporting the last named shaft, studs mounted on thebearings, and a coiled spring surrounding each of the studs foryieldingly retaining the last named shaft in said driving engagementwith the wheel.

In testimony whereof I afiiX my signature.

JOSEPH S. ULATOWSKI.
